To all fuflzom it may concern.'

Bo it known that l, JOHN W. GRANTLAND, a citizen of the AUnited States, residing at lhilr-ulelphia, county of Philadelphia, and Stato of Pennsylvania, have invented a certain new and useful Improvement in Faucets, of which the follmving is a specification.

My invent-'ion relates to a new and useful improvement in faucets, and has for its object to provide an exceedingly simple and effective construction by which a faucet may be made of but two parts requiring no pac-.king around the stein, and yet will be absolutely prevented from leaking.

lilith these ends in view, this invention consists in the details of construction and conihin ation ot elements hereinafter set forth and their specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to ina-ke and use the same, I will describe its construction in detail, referring by letter te the accompanying drawing form-` ing a part of this specification, in which- Figure l is an end elevation of my 'iinproved faucet; Fig. 2 is a central section thereof showing the faucet in a closed position.A Fig. 3, a similar view of a slightly modified form of the plunger, the latter also being in section.

ln carrying out my invention as here enilmdied, A represents the body or casing of the faucet which has formed therewith the sp'ace being furthe purpose set forth.

li` represents the plunger the inner end of which Vis threaded so -as to engage the threads 4of the opening formed throughthe center of the diaphragm by means of'which "the plunger .is fed up or down by the revolving of the handle G. The upper portion of the plunger is enlarged to approximately it the opening M in the'casing as clearly shown in Fig. 2,

`Sli-while the inner end of the plunger has secured thereon a'washer H adapted to seat upon the valve seat I.

The outlet J of the faucet is slightly contracted by the curve K, and in practice-the object of this curved portion is to direct the water vflowing from the faucet across the projecting edge C/ of the d.ia} hrag1n and this produces a partial vacuum in the space E, the effect of vwhich is to cause a suction in this space when the wat-er is flowing and prevent any leakage around that portion of the plunger loosely fitted inthe opening in the casing.

l have found by actual demonstration that but very little water will pass from the space D to the space E around the threaded portion of the plunger, but what little water does escape in this direction will be drawn out at the outlet of the faucet by the suction above described. A portion of the casing wall is sufficiently larger than the stein '.to form therewith a ch amber through which air -may pass into the last named space and through which the plunger and valve' may be withdrawn. 0f course when the faucet .is close-d the washer H fitting upon the valve seat will prevent any leakage.

K is made of'but two castings and does not re- 4`quire any packing, and therefore the cost of. 'manufacture of the ordinary form of faucets is greatly reduced.

In Fig. 8 I have shown a slight modification of my improvement in which both the inner and outer portion of the plunger is threaded, both threads being of the same pitch, and this makes a better it between the plunger and casing and is more economical to manufacture than the making of a snug iit between the outerportion of the plunger and the casing as shown in Fig. 2, but in both cases the principle remains the same, 'in that a partial vacuum is created in the space E absolutely preventing any leakage when the faucet is open andthe water running.

Of course I do not wish to be vlimited to its minor details as the same might be varied Within certain limits Without in any wise departing from the spirit of my invention..

By my invention as described and shown,

a paokless relation between the valve stem, and the neck ofthe casing.

Having thus fully described' my invention, what I claim as new and useful, isf- A packless faucet consisting` ofa casing` having a diaphragm therein forming two spaces, one space permitting the iiow of water when the faucet is open and the other space tending to create a partial vacuum for I have constructed a two-part faucet having drawing off any Water eakng into the spaoe,' In testimony whereof, I have hereunto afa valve. and stem 'mounted m the casmg, a fixed my slgnature 1n the presence of two ortlon of the Casing Wall belng sufolently Subrsorlblng wltnesses.

arger Vthan the stem to form therewith a v JOHN W. GRANTLAND. 5 chamber through which airl may pass into VVitnesss:

lthe last named space and throughwhioh the H. RoB'ELzaT MAYS,

plunger and Valve may be' Withdrawn. CHAS. G. HAWIUNS.
